Library which uses modified run-length encoding to do basic morphological operations on binary images (dilation and erosion).
Algorithm is taken from paper Fast Algorithms for Binary Dilation and Erosion Using Run-Length Encoding
Features:
- Dilation
- Erosion (implemented but with custom algorithm instead with algorithm in paper)
- Optimize implementation
Intel i7-8750H, 6 cores, linux 5.4.23_1
